We retrieved the fecaliths, followed by removing the appendix. After surgery, a slight fever and paralytic ileus prolonged for several days. We suspected an intra- abdominal abscess, and CT scan of abdomen was done. The CT scan revealed small, high-density areas in the peritoneal cavity, which were compatible with retained fecaliths, and small abscesses around them (Figure 2A–B). As the patient refused further surgery, we administered antibiotics and decompression with a nasogastric tube. Fortunately, his symptom improved, and he was discharged after 22 days of surgery. Three months later, a check-up abdominal CT scan was done. The CT scan revealed no intra-abdominal abscess and the fecaliths had disappeared (Figure 3). DISCUSSION Acute appendicitis is one of the most common surgical emergencies in daily practice. It affects approximately 7% of the population over the lifetime [2]. There are Figure 2: (A, B) Computed tomography scans of axial and coronal several complications after appendectomy and the most views of the abdomen.

Methods: Using the PubMed literature search engine to find all English references of “intussusception” and “appendix”, and reviewing those that contained actual case reports of intussusception of the appendix, we analyzed the demographics, presentation, diagnostic methods, surgical treatment, and histology from 140 articles representing data from 181 patients.

  • Twisted Bowels: Intestinal Obstruction Blake Briggs, MD Mechanical
    Twisted Bowels: Intestinal obstruction Blake Briggs, MD Objectives: define bowel obstructions and their types, pathophysiology, causes, presenting signs/symptoms, diagnosis, and treatment options, as well as the complications associated with them. Bowel Obstruction: the prevention of the normal digestive process as well as intestinal motility. 2 overarching categories: Mechanical obstruction: More common. physical blockage of the GI tract. Can be complete or incomplete. Complete obstruction typically is more severe and more likely requires surgical intervention. Functional obstruction: diffuse loss of intestinal motility and digestion throughout the intestine (e.g. failure of peristalsis). 2 possible locations: Small bowel: more common Large bowel All bowel obstructions have the potential risk of progressing to complete obstruction Mechanical obstruction Pathophysiology Mechanical blockage of flow à dilation of bowel proximal to obstruction à distal bowel is flattened/compressed à Bacteria and swallowed air add to the proximal dilation à loss of intestinal absorptive capacity and progressive loss of fluid across intestinal wall à dehydration and increasing electrolyte abnormalities à emesis with excessive loss of Na, K, H, and Cl à further dilation leads to compression of blood supply à intestinal segment ischemia and resultant necrosis. Signs/Symptoms: The goal of the physical exam in this case is to rule out signs of peritonitis (e.g. ruptured bowel). Colicky abdominal pain Bloating and distention: distention is worse in distal bowel obstruction. Hyperresonance on percussion. Nausea and vomiting: N/V is worse in proximal obstruction. Excessive emesis leads to hyponatremic, hypochloremic metabolic alkalosis with hypokalemia. Dehydration from emesis and fluid shifts results in dry mucus membranes and oliguria Obstipation: severe constipation or complete lack of bowel movements.

  • Delayed Presentation of a Retained Fecalith
    Open Access Case Report DOI: 10.7759/cureus.15919 Delayed Presentation of a Retained Fecalith Fawwad A. Ansari 1 , Muhammad Ibraiz Bilal 1 , Muhammad Umer Riaz Gondal 1 , Mehwish Latif 2 , Nadeem Iqbal 2 1. Medicine, Shifa International Hospital, Islamabad, PAK 2. Gastroenterology, Shifa International Hospital, Islamabad, PAK Corresponding author: Fawwad A. Ansari, [email protected] Abstract A fecalith is a common cause of acute appendicitis, and laparoscopic surgery is the mainstay of its management. Literature review shows that a fecalith may be retained in the gut following a laparoscopic appendectomy in some rare cases. In most cases, the fecalith becomes symptomatic with time due to the formation of an abscess, fistulous tract, or inflammation of the appendicular stump (stump appendicitis). We report a case of retained appendicular fecalith presenting with symptoms similar to acute appendicitis, 15 years after laparoscopic appendectomy. Categories: Gastroenterology, General Surgery Keywords: colonoscopy, acute appendicitis, appendectomy, fecalith, right iliac fossa pain, complications Introduction A fecalith is a hard stony mass of feces in the intestinal tract. Fecal impaction occurs when a large amount of fecal matter gets compacted and cannot get evacuated spontaneously [1]. In its extreme form, fecal impaction can lead to the formation of a fecalith due to the hardening of fecal material that forms a mass separate from other bowel contents [2]. It can occur in any part of the intestine [1]. Most often, a fecalith arises in the colon (mostly sigmoid) or rectum and very rarely in the small intestine [2]. Here we present a case of a retained appendicular fecalith in a patient who presented with an acute abdomen.

Amyand’s hernia, named for the first person to describe an inguinal hernia containing the vermiform appendix, is an uncommon variant of an inguinal hernia. Amyand’s hernia is an extremely rare condition and is often misdiagnosed. Traditionally, these hernias have been diagnosed at surgery but are increasingly diagnosed by abdominal computed tomography (CT) scans. CT of the abdomen may help in guiding the diagnosis. 1.
